WINDOW-SCREEN.

SPECIFICATION formngpart of Letters Patent N o. 709,405, dated September 164, 1902.

I Application filed February 13. 1899- Serial No. 705,449. (No modali:

To al?. whom, it may concern:

Be it known that I, EsPIRIDIoN HIPoLITo,

residing at Los Angeles, in the county of Los `perior `means whereby the screen -sash is mounted between the blind-stops of the win-V dow-opening without planting any stops on the blind-stopfor such purpose; also, to provide superior means for the, ready removal and replacing of the screen.

Another object is to provide superior means for adjusting the tension of the springs which hold the sash in place in the window against the force of gravity, so that although the sash will beheld by friction Where put it can be moved up and down with a minimum expen- Another object is to provide superior means for fastening the screen` to the sash.

The accompanying drawings illustrate my` to contract the View Vand other parts arebroken to expose interior construction. Fig; 2 is a plan section on Airregular line 2 2, Fig. l. Fig. 3 is an exaggerated plan of a blank for forming the collar-plate forthe tongue- Fig. i is a section of the same on line 44, showing the collar-hole countersunk to admit the adjusting-screw. Fig. 5 is an exaggerated View to show `the adjusting device in process of manufacture. The collar-plate, the anvil, and the hollow punch for swaging the collar are shown in section. Parts are broken awayy to contract the View. Fig. 6 is a fragmental detail of the finished adj listing-screw and collar.

A A indicate the grooved stiles of the sash.

o: of the and screwed into the stop E, which is made of hard Wood, so as to form a nut for the screw. The adjusting-screw Fhas an annular groovef at its outer end and is preferably provided with athumb-piecef, by which it can be readily turned.

G indicates a collar-plate which forms a collar extending into the groovef. rllhe collar-plate is fastened to the stile by nails H, driven through `the holes g in the collar-plate v and into the stile.

The method of manufacturing the adjusting device comprising the screw provided with a collar-plate consists in first perforating a blank of brass or other suitable metal, as at 1, Fig. 3, then countersinking the perforation 2, which is intended for the screw, then placing the same upon an anvil `3,With the screw inserted up through the countersunk hole 2, as shown in Fig. 5, then by means of a hollow punch or swage L swaging the countersunk portion 5 of the plate back into position, and thus into the annular groovefof the screw. When the parts are assembled, the hole 2 in the collar-plate is ,smaller than the body of the screw and is concealed within the annular groovef of the screw.

The screen-netting is fastened in the screen in the following manner: The stiles A A' and rails A" A are rabbeted, as at 6,`and in the seat of the rabbet at a distance from and between the edges of said seat inwardly-sloping oblique saw-kerfs 7 are cut, and when the frame is assembled the wire-nettingS iis bent into the channels formed by the saw-kerfs,

ICO

and strips of molding 9 are laid in the rabbet` to extend over and on both sides of the sawkerf therein and fastened by nails 10 to hold the wire in place on the seat of the rabbet.

In practice the screen is inserted into the window by first turning the screws F to withdraw the tongue E into its stile, then. pressing back the tongue C and inserting it into the groove b' in the blind-stop B. Then the sash is brought into rproper position to make the tongue E register with the groove b. Then the screws F are turned to force the tongue E outward into its groove b in the blind-stop B. Any required pressure for causing friction to sustain the sash can be applied by turning` the screws, thus to press the springs D D irrnly against the staples cl to force tongue C outward. By extending the molding-strips on both sides of the groove room is provided for driving the nails l0 into their respective stiles and rails beyond the groove without interfering with the wire-gauze.

Now, having described my invention, what I claim as new, anddesire to secure hy Letters Patent, is v y 1. In a screened Window, the combination of grooved stilcs; a tongue in the groove of one stile and provided with transverse grooves extending into x the tongue from one side; staples set in the tongue and extending over the mouths of the grooves respectively; bowsprings in the stile-groove and respectively fastened at one end, saidtongue being seated in the stile-groove with the staples resting upon the bow-springs5 nails set through the stile and passing through the slots respectively; a tongue in the groove of the other stile; and means for adjusting the pressure of the tongues.

2. lA screen comprising a frame, the stiles and rails of which are rabbeted and are provided with undercutchannels extending along in the seats of the rabbets, respectively, be-

tween the edges of said seats,respectively,and sloping obliquely inward behind said seats; a wire sheet seated upon said seats and having its edges underbent into said channels; molding-strips on the wire sheet in the rabbets and respectively extending on both sides of their respective channels; and nails driven obliquely through the molding-strips into the seats respectively beyond the channels.

3. A screen comprising a frame, the stiles and rails of which are rabbeted and are provided With undercutchannels extending along in the seats of the rabbets, respectively, between the edges of said seats, respectively, and sloping obliquely inward behind said seats; a wire sheet seated upon said seats and having its edges yunderbent into said channels; and molding-strips fastened on the wire in the. rabbets and respectively extending on both sides of their respective channels.

4. In a Window, the combination of a grooved stile; a tongue moving in the groove in said stile; a collar-plate; and an adjusting-screw through the plate, said screw consisting of a screw-threaded portion and a body portion, the body portion being provided at the end opposite the screw-threaded portion with an annular groove; said collarplate being fastened to the stile on thel edge thereof opposite the groove, and said adjusting-screw being inserted through a hole in
